1.0 GENERAL

The Storage/Control I/O Module performs two functions: to connect outside interfaces to the
system controller and to house the hard disk drive. It plugs into the back of the VCO/4K system
and provides the I/O interfaces for system peripheral devices and host communication links
using four serial ports, one Ethernet port, one printer port and one SCSI connector. Figure 1 is
an illustration of the front panel of the Storage/Control I/O Module.
Physical interfaces to host computers and peripheral devices are provided on the front panel of
the Storage/Control I/O Module. Two serial ports are available for SIO host links, and another
two are dedicated to supporting the local system administration console and a remote
maintenance modem. An Ethernet Transceiver interface and parallel printer connector are
also located on the Storage/Control I/O Module.
